Hey guys, been working with the wiring on my truck, and I have an issue. The fuel guage is now keeled over to about the 3oclock position. From using the search feature I have figured out that that probably means I have cut a wire somewhere, and that the guage is receiving an open circuit. Where does the wiring for the fuel guage run through the firewall at? Is it at the fusebox, or is it through this other little grommet on the firewall, behind and above the drivers side valve cover? Its 2 wires, runs down to a gray connector, and then on down under the truck. Help.
